I have a picture of a pair of wild wallabies and one of them even had a little joey's head poking out of the pouch. Just to reinforce my Australianess when dealing with European customers.
One of the ones I used during 2020 was a biohazard screen from Resident Evil. Another was from Rogue One, with a nice shot of the Death Star getting ready to fire. I think it set the right tone.
